Definitions

  • the invention relates to a ventilation device for
  • Fuel tanks of vehicles with a vent valve and a filler neck, which is associated with a ventilation line to the fuel tank.
  • a venting device for a fuel tank for a motor vehicle from DE 37 44 175 C2.
  • a first vent line with Umsehaltventil from the fuel tank to a first filter and a second vent line from the fuel tank to the first or a second filter is provided.
  • a vent line is provided within the filler neck between the filler neck and the compensation volume, so that the upcoming fuel in the filler neck can flow.
  • the invention has for its object to form a venting device and to arrange so that in a simple way excessive loading of the vent filter and a fuel vapor outlet from the tank neck is prevented.
  • the ventilation line has a separate, the refueling volume flow adaptable reducer. This ensures that adjusts a recirculation flow between the fuel tank and the filler neck, the fuel flow corresponds to the refueling and even with large fuel flow sufficient
  • Circulation volume flow stimulated by the Saugstrahl bin the incoming fuel jet, between the fuel tank and the filler neck is ensured.
  • the filler neck has a reduced to the diameter of a fuel gun opening cross-section and the ventilation duct with respect to the Strömurigsraum after.
  • the cross-sectional reduction of the filler neck is arranged, wherein the reduced opening cross-section of the filler neck has a sealing element for the fuel gun trunk in the manner of a diaphragm or a flexible plastic lip.
  • the reducing member is designed as a level-dependent float valve.
  • the reducer is designed as a flow-dependent needle valve or as a circulation valve with a flow-dependent opening cross-section and that the circulation valve has a valve chamber, a nozzle and a nozzle corresponding to the formed as a float needle, wherein the needle by a biasing member is biased against the nozzle.
  • the needle valve is basically closed and opens its flow cross-section corresponding to the ventilation volume flow resulting from the refueling. It is advantageous for this purpose that the circulation valve with respect to the vent flow at the end of the ventilation duct or directly in front of the filler neck, is arranged. Thus, filling of the ventilation duct with fuel is prevented.
  • the ventilation duct is indirectly connected via a ventilation valve to the fuel tank and directly to the ventilation valve. This ensures a simple connection to the tank and possibly also a simple retrofitting of the recirculation line.
  • the vent valve is associated with a filter via a filter line, wherein the vent line is arranged on the vent valve or on the filter line.
  • the recirculation line or the recirculation valve designed as a needle valve serves to relieve the filter, since no excessive fresh air volume flow is sucked in by the suction jet effect during refueling.
  • the fuel tank air present on the ventilation valve can flow both directly from the ventilation valve and via the filter line into the recirculation line.
  • the opening of the ventilation duct in the filler neck and the filler neck are formed such that the fuel tanks sucked during refueling of the fuel tanks by the Saugstrahl mono sucked from the tank interior through the ventilation duct.

Abstract

L'invention concerne un dispositif d'aération pour réservoirs de carburant (1) de voitures particulières, présentant une tubulure de remplissage (3) et une soupape d'aération (2) entre lesquelles se trouve une conduite d'aération (4) servant de conduite de recirculation empêchant une arrivée excessive d'air frais grâce à l'effet de jet aspirant lors du remplissage du réservoir. Cette conduite de recirculation présente en outre une soupape (5) dont le pointeau se présente sous la forme d'un flotteur et qui fait varier la section d'écoulement de la conduite d'aération (4).
